AUTOMATIC LOCKING GAS-COCK.

Specification of Letters Patent.

Patented Mar. 7, 1916.

Application filed April 10, 1914. Serial No. 830,863.

To all whom it may concern:

Be it known that we, ELMER BARGER and WILLIAM FonLL, citizens of the United States, and residing in Peekskill, county of WVestchester, and State of New York, have invented a new and useful Improvement in Automatic Looking Gas-Cocks, of which the following is a specification.

This invention relates to stop cocks, and particularly to gas cocks as used on domestic gas burning utilities.

The object of the invention is to provide a locking cock that shall be easy to construct, comprise the smallest number of parts possible, and be plain and easy to operate without being liable to careless and accidental operation. The objects are attained by the means set forth in these specifications and the accompanying drawings, in which letters of the same kind refer to the several parts in the different drawings.

Figure 1 is a side elevation of a gas cock with the lock attachment. Fig. 2 is an end view of the gas cock, the locking devices shown in transverse section. Fig. 3 is an end view of the gas cook partly in cross section showing the operation of the locking devices.

The invention is shown as applied to gas cocks as most commonly used upon gas ranges, stoves, heaters, &c.; but it is equally applicable to all forms of plug cocks. In Fig. 3 the entire construction is shown. Ordinarily the device will not require any change from the usual form of the body a of the cock, which has a notched out portion at the top as shown particularly in Figs. 1 and 33, leaving a depressed surface 7 and shoulders at n for the traverse and lodgment of the plug stop 6.

To attach the look a hole is bored longitudinally in the outer end of the plug b to receive a pin 2' and a spring '21. A slot, as at m is made in the side of the plug and intersects with the longitudinal hole. A latch Z Z is pivoted within the slot upon a pin t,

and one end of the latch lies within the lon gituclinal hole, the other end Z of the latch projects from the side of the plug and is adapted to fall within the space between the shoulders n W, as in Figs. 1 and 3, being so related to the stop 6 that when the stop is against the shoulder 12, which will be when the cock is closed, the latch will lie against or very close to the shoulder a, so that the cock cannot be opened until the latch is raised.

Above the latch is a pin c that rests upon the latch, and a springo lies under the latch. 11 part of the push pin 2' is reduced in size as at 1", which leaves a recess 8 around that portion of the pin. The screw d that secures the handle 0 to the plug, has its screw end u of a length to project into the recess 8, as shown in Figs. 2 and 3, and the screw end forms a sto to retain the pin within the plug and to limit the movement of the pin. Depressing the pin lifts the latch and admits of the turning of the plug to open the cock, as in Fig. 3. In closing the cock the latch automatically drops to the locking position as shown in Figs. 1 and 2.

Having described our invention, what we claim and desire to secure by Letters Patent, is-

In an automatically locking gas cook, the combination with the plug of the cock and the stop shoulders on the body of the cook, a latch pivoted in a slot in the side of the plug of the cock, a pin operating in a hole longitudinally of the plug, an arm of the said latch extended under said pin, a spring under said arm of the latch, a portion of the pin reduced to form a recess, and a screw for attaching the handle to the plug one end of the said screw projecting into the recess in said pin.

Signed at Peekskill, in the county of Westchester and State of New York, this 4th day of April, 1914.
